Got this package tour. Though it took a few days to confirm because they said the tour operator needs a certain number of booking (I booked a month early) before the tour pushes through which is understandable. They managed to confirm it after a few days, special shout out to Bernadette who followed it up for me. She handled my concern efficiently.
The tour itself was great, being able to see 4 sites in one day but kinda rush with time so if you prefer to stay in one site longer then do a separate tour for each site, but for us, this tour had worked well as we don't have a young child or a senior with us.
The majority of tourist in our bus are locals (japanese) and so the tour guide can only speak little english but he tried his best to explain the sites to us.
I will highly recommend this tour. Value for money!
